The legislation set out by HMRC

What is the legislation set out by HMRC?

The legislation, which came into force on 1 January 2010, means that it is compulsory for
companies to send their Company Tax Return online using iXBRL for accounts and computations.

Effective on or before 1 April 2011 for any accounting period ending after 31 March 2010,
UK company tax returns must be filed online to HMRC in Extensible Markup Language (XML) with
the accompanying statutory accounts and tax computations in the inline variant of the
eXtensible Business Reporting Language (XBRL) format known as inline XBRL (iXBRL).

The general impact on allUK companies

What is the general impact on all UK companies?

Companies will need to ensure their internal process and systems
that support tax return and statutory accounts preparation will
enable them to meet the HMRC requirement.

The introduction of iXBRL may affect processes in some companies,
including those who currently assemble data in text-based software
such as Word or Excel and then send this in text files, such as PDF,
to Companies House and HMRC. They will need either to use
appropriate iXBRL 'conversion' software or to change their
processes so that a third party handles the very labour intensive
tagging process for them.
